Best Koji alternatives in 2026 compared

A note on fairness and accuracy: This comparison is based on publicly available information and secondary research. Vendors update their pricing, features, and positioning over time, so please confirm the current details with each provider directly before you decide. We aim to be objective and fair. Every company covered here is a strong option in the space, and the best choice depends on your specific needs.

If you are evaluating Koji alternatives, here is the short answer: the right platform depends on whether you prioritize verified B2B participants, transparent per-interview pricing, multilingual qualitative depth, or EU data residency. Koji is a strong AI-native customer interview platform with transparent credit pricing and strong compliance posture, but it is one of several good options, and for professional and B2B research the biggest differentiator across the category is how participants are verified. This guide compares eight platforms so you can match the tool to your research.

One quick note first: there was an unrelated consumer link-in-bio and mini-app product also called Koji that shut down, which sometimes causes confusion. The Koji in this guide is koji.so, an AI-native customer research platform. According to its public materials, it is built in Amsterdam, runs research-grade interviews via voice, chat, or phone, interviews in 30+ languages with native phrasing, and synthesizes themes, sentiment, and quotes into shareable reports, with EU data residency and SOC 2 Type II and ISO 27001 certifications cited. We cannot independently confirm every claim, so treat the detail below as a starting point and verify specifics with each vendor.

What Koji does, and why teams compare it

Koji is an AI-native customer research platform built around adaptive interviews. Based on its public positioning, an AI consultant drafts the brief from your research question, an AI interviewer runs voice, chat, or phone conversations around the clock with follow-ups that adapt per participant, and an AI analyst scores transcripts, extracts themes, and aggregates structured answers in real time. It supports 30+ languages with native phrasing and accents so you skip a separate translation step, offers EU data residency, and cites GDPR compliance alongside SOC 2 Type II and ISO 27001 certification, with a promise that data is never used to train models. Pricing is a per-interview credit model, with public materials citing figures as low as about 1 euro per qualified text interview and about 3 euros per qualified voice interview, plus a free start. That makes it attractive to product teams, founders, and agencies that want fast insight without a dedicated researcher.

That blend of transparent per-interview pricing, strong compliance, and native-language interviews is the draw. Teams still shop for alternatives for a few reasons: they need verified professionals for B2B work rather than a bring-your-own audience, they want recruitment and interviewing bundled in one platform, they prefer a specific regional panel, or they want deeper synthetic pretesting or live multi-respondent formats. Your priority decides which option below fits.

How to choose your platform

Choose CleverX if you run B2B or professional research and need participant verification you can defend. CleverX recruits from a panel of 10M+ professionals verified by work email, LinkedIn, licence, and a recorded interview across 150+ countries, then runs AI-moderated interviews and surveys with those same people, with results typically back in days. Compared with a bring-your-own audience, the verified professional pool is the key upgrade for B2B.

Choose Koji if you want transparent per-interview pricing, EU data residency, strong compliance certifications, and native-language voice, chat, or phone interviews for your own audience.

Choose Yasna if multilingual qualitative depth across many markets with transparent self-serve pricing is your main requirement.

Choose Strella or Conveo if you want agentic voice interviews with dynamic follow-ups and a panel or your own audience.

Choose Outset or Listen Labs if you already own an audience and only need the interview and synthesis layer.

The eight alternatives in detail

1. CleverX

CleverX is an end-to-end research platform built around verified professionals. You define a target audience by job title, seniority, industry, company size, and geography, CleverX sources and vets participants, and you run AI-moderated interviews, surveys, and expert interviews with those same people. Studies are hosted end to end, and results typically come back within days.

Against Koji, the difference that matters for professional research is recruitment and verification. Koji is strong on the AI interview and analysis layer, with transparent pricing and a solid compliance posture, and it works well when you can bring your own audience. CleverX verifies every participant by work email, LinkedIn, licence, and a recorded interview, which is designed to keep professional fraud and misrepresentation out of your sample, and it supplies the panel. If your research targets employed professionals and hard-to-reach B2B roles, CleverX is the natural fit. Book a demo with CleverX to preview your audience first.

2. Yasna

Yasna is a Bratislava-based AI-moderated qualitative platform that runs text, voice, and video interviews in 45+ languages across many markets, with transparent self-serve pricing and recruitment through partners or your own audience. It is a strong match if multilingual qualitative work is your focus. See our Yasna alternatives guide.

3. Keplar

Keplar is a San Francisco voice AI research platform, founded in 2022 and backed by Kleiner Perkins, that runs AI-moderated voice interviews, builds digital twins for early testing, and uses research agents to draft guides and synthesize results. It leans toward consumer insight at scale. See our Keplar alternatives guide.

4. Strella

Strella is an AI customer research platform with an agentic voice moderator that runs conversational interviews with dynamic follow-ups and near real-time synthesis. It offers its own panel and supports bringing your own audience, which makes it a strong voice-first alternative to Koji. See our Strella alternatives guide.

5. Conveo

Conveo is an AI qualitative platform with an agentic voice moderator, multilingual support, and fast synthesis, suited to teams that want conversational interviews across languages. It is a direct alternative to Koji for agentic qual. See the Outset vs Conveo vs CleverX breakdown.

6. Tellet

Tellet is an Amsterdam-based AI research platform, founded in 2023, that runs conversational voice, video, and photo interviews in well over 50 languages, with hybrid recruitment through your own customers or integrated panel partners. It is a strong match if multilingual consumer qualitative work is your focus. See our Tellet alternatives guide.

7. Outset

Outset is an AI interview engine for your own audience. You build a guide, send a link, and the AI runs conversational interviews and generates synthesis. It does not supply participants. See our Outset alternatives guide.

8. Listen Labs

Listen Labs runs AI-moderated interviews at scale for product and insights teams, surfacing themes automatically. Our CleverX vs Listen Labs comparison covers the differences, including recruitment and verification.

Compliance is strong, but who you interview still decides the result

Koji’s compliance posture is a genuine strength. EU data residency, alignment with the GDPR, SOC 2 Type II, and ISO 27001 certification matter for enterprise procurement and for any team handling sensitive data, and they are real reasons to shortlist it. But data security and sample quality are different problems. A perfectly compliant interview is only as valuable as the person on the other end, and in qualitative research a single unqualified or fraudulent respondent can distort a small sample enough to send a decision the wrong way.

Research bodies such as ESOMAR and the Insights Association treat respondent authenticity and sample quality as central to valid research, and the spread of AI-generated responses and professional survey-takers has made verification more important, not less. Sampling guidance from the Pew Research Center and interview best practice from the Nielsen Norman Group both make the same case: reaching the right people is the hard part. This matters most in B2B, where you need not just a real person but the right person: the specific job title, seniority, and employer. When you pilot Koji alternatives, ask each vendor exactly how it confirms identity and employment, especially where you bring your own audience. For frameworks, see our AI-moderated interview platform buyer guide and the explainer on what AI-moderated interviews are.

Pricing: compare cost per usable interview

Koji’s transparent per-interview credit model is a welcome contrast to the quote-only pricing common in the category, and public materials cite figures as low as about 1 euro per qualified text interview and about 3 euros per qualified voice interview, with a free start. That is genuinely useful for budgeting. The headline rate is rarely the whole cost, though. A low per-interview price against an audience you have to source yourself still carries the cost of finding and screening the right people, and for hard-to-reach professionals that sourcing often dwarfs the interview fee.

When you request quotes, ask each vendor to price a realistic study: your exact audience, sample size, studies per quarter, and whether recruitment and verification are included. Bundled models like CleverX fold recruitment and platform access into one number, which often compares well once you account for the cost of finding verified professionals.

The bottom line

Koji is a strong AI-native customer interview platform with transparent per-interview pricing, native-language interviews, and an enterprise-grade compliance posture, and for teams that bring their own audience it is a genuinely good choice. But the category offers real alternatives, and the best fit depends on your priorities. For B2B and professional research where verified participants are non-negotiable, CleverX is the closest match. For multilingual qualitative depth, Yasna fits. For agentic voice qual, Strella and Conveo work. For your own audience, Outset and Listen Labs are the specialists. Pilot two or three before you commit, make sure you are evaluating the research tool at koji.so rather than the unrelated defunct app, and treat participant verification as a first-class requirement, not a detail.

Frequently asked questions

What is the best Koji alternative in 2026?

It depends on your priority. If you need AI interviews with a built-in panel of verified professionals, CleverX is a strong fit, with 10M+ verified B2B and B2C participants across 150+ countries. For multilingual qualitative depth with transparent pricing, Yasna is worth a look. For agentic voice interviews with a panel, Strella fits. Confirm current details with each vendor before you commit.

What does Koji do?

Based on its public materials, Koji is an Amsterdam-based AI-native customer research platform that runs research-grade interviews via voice, chat, or phone. An AI moderator asks adaptive follow-ups, interviews run in 30+ languages with native phrasing, and the platform synthesizes themes, sentiment, and quotes into shareable reports. It cites EU data residency, GDPR compliance, SOC 2 Type II, and ISO 27001 certification, with per-interview credit pricing.

Is Koji the same as the old link-in-bio app?

No. There was an unrelated consumer link-in-bio and mini-app product called Koji that shut down, which can cause confusion. The Koji covered here is koji.so, an AI-native customer research and interview platform built in Amsterdam. Always confirm you are evaluating the research tool at koji.so before you compare or buy.

Which Koji alternatives verify participant identity?

Verification depth varies across the category. CleverX verifies every participant by work email, LinkedIn, licence, and a recorded interview, which is designed to keep professional fraud out of B2B samples. Many AI interview tools rely on bring-your-own-audience models or third-party panels, so ask each vendor exactly how it confirms identity, and for B2B, employment and seniority, before you buy.

How much does Koji cost compared with alternatives?

Koji uses a per-interview credit model, with public materials citing figures as low as about 1 euro per qualified text interview and about 3 euros per qualified voice interview, and a free start with a small number of credits. Others quote custom enterprise pricing. The number that matters is cost per completed, usable interview with the right participant, since recruitment usually dominates total cost, so price a realistic study with each vendor.

Does Koji recruit participants for you?

Koji centers on the AI interview and analysis layer and supports interviewing your own audience, with recruitment options for sourcing participants. If verified professional or B2B participants are critical, confirm exactly how any recruitment source vets respondents, since the panel behind an AI interview tool usually matters more than the AI itself.
